' removable window-sashes wherein strips are used to hold and guide thesash and to permit its removal from the frame when itis to be cleaned.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claim.l

Figure I is an elevation, part in section, illustrative of my invention.Fig. II shows part of the window-frame and shows the upper and lowersashes in their outer or cleaning position. Fig. III is an enlargedhorizontal section, the upper half of the iigurebeing taken on line IIIIII, Fig. IV, and the lower half of the iigure being taken on line IIIIII, Fig. V, the slotted plate of Fig. IV, however, being shown in edgeview in Fig. III. Fig. IV is a sectiontaken on line IV IV, Fig. III,with a portion of the strip broken away. Fig. V is a similar view takenon line V V, Fig. III. Fig. VI is a section taken on line VI VI, Fig.VIII. Fig. VII is a section taken on line VII VII, Fig. IX. Fig. VIII isa section taken on line VIII VIII, Fig. VI. Fig.

IX is a section taken on line IX IX, Fig.

VII. Fig. X is a detail side lview, part in section.

Referring to the drawings, l represents the lower, and 2 the upper, sashof a window. 3 represents the window-frame.

4 represents the weight-cords passing over pulleys 5, as usual.

6 represents strips, which in this instance are secured to and carriedby the sash and are adapted to be moved into grooves 7, formed in thewindow-frame. The strips are so secured to the sash as to enable them tobe moved into the grooves 7 of the windowframe, as shown in the upperpart of Fig. III and in Figs. IV, VI, and VIII, when they serve to holdthe sashin using position and to guide the sash in its verticalmovement,

and the strips are capable of being moved out of engagement with theframe, as shown in the lower part of Fig. III and in Figs. V, VII, andIX, when the sash can be moved out of vertical position and into aposition where it can be readily cleaned, as shown in Fig. II.

My preferred means of securing the strips to the window-sash is by meansof plates 8,

which I have shown in the form of disks, and which are secured to thesash by means of screws 9. These plates have angular slots l0 to receivepins 1l, that pass through the strips 6,and on the inner ends of thepins are washers or nuts 12, that it in recesses 13 in the sash, asshownY in the lower part of Fig. III. The plates and pins thus hold thestrips to the sash, while the slots in the plates permit the strips tobe moved into and out of engagement with the window-frame, as explained.

As a means for movin the strips I have shown them provided with racks14, corresponding in shape to the slots l0, and which are engaged bypinions 15 on shafts that are provided with non-circular ends 16 toreceive a suitable key. The pinions are carried by` and located on theinside of the strips 6, and the racks 14 are secured to the window-sashby means of screws 17 or otherwise.

. By utilizing the strip to hold and guide the sash when in usingposition and permitting the sash to be .moved out into cleaning positionI attain the advantages set forth in my application for patent iledherewith, and by securing the strips to the sash the work can be done atthe factory, and all that is necessary to do in putting the sash inAplace is to form the groove in the frame.

I claim as my invention- In a removable window sash, the combination ofa sash, slotted plates secured to the sash, strips movably secured tothe sash by means of pins tting and working in the slots of said platesand means consisting of a rack ofthe same shape as the slots secured tothe strips and a pinion carried by the sash and in engagement with therack, for moving the strips substantially as andfor the purpose setforth.
